About
Silicone rubber is an elastomer consisting of silicone polymers and filler materials. It is widely used for sealing applications and is available in various formulations.
Room-Temperature-Vulcanizing, or RTV Silicone, cures at room temperature and offers good resistance to vibration, shock (mechanical stress), chemical corrosion, and heat.
Silicone sealants are used as form-in-place gaskets for engine and transmission applications, sealing of exterior joints, aquarium panes, bath tubs, in construction and glazing applications, electrical potting and encapsulation, mould making, etc.

RTV silicone systems cure in humid conditions. Humidity should be maintained until the curing process is completed. The curing process cannot be accelerated using heat. Excessive heat can adversely impact the curing process.
